weiche 0.10.0

A wrapper around the DB Website API for querying train connections.

🚆 weiche

This is an unofficial library wrapper around the API of the Deutsche Bahn (DB) website for identifying connections. It returns realtime, live data. If you do not need this in your project I strongly recommend not to use this API as it might break any moment if DB changes the API for getting station and train connections.

It has a API compatibility layer to the schiene package for easy drop-in replacement as schiene no longer works.

Requirements

• Python 3.10 and above
• requests package for the synchronous API and Schiene wrapper
• aiohttp for the asynchronous API

Features

• Get connections between two stations
• Search stations by name
• Get station information

Setup

$ python -m venv /path/to/venv $ /path/to/venv/bin/python -m pip install weiche[sync,async,schiene]

Usage

Use the synchronous API

from datetime import datetime
from weiche import SynchronousApi

api = SynchronousApi()

amsterdam_query = api.search_locations('Amsterdam', limit=1)
amsterdam = amsterdam_query[0]
munich_query = api.search_locations('München Hbf', limit=1)
munich = munich_query[0]

api.search_connections(
    at=datetime(2025,5,10,18,0,0),
    from_location=munich.id,
    to_location=amsterdam.id,
    limit=10,
)

You can also add an HTTP proxy to connect via as Bahn tends to block server ip addresses.

from weiche import SynchronousApi

api = SynchronousApi(proxy="192.168.0.1:8888")

Response from Synchronous API

The return format is an object which can also be found in the objects.py file.

Look for the Connection class and see the API definition there.

Use the asynchronous API

import asyncio
from datetime import datetime
from weiche import AsynchronousApi

async def search():
    api = AsynchronousApi()

    amsterdam_query = await api.search_locations('Amsterdam', limit=1)
    amsterdam = amsterdam_query[0]
    munich_query = await api.search_locations('München Hbf', limit=1)
    munich = munich_query[0]

    return await api.search_connections(
        at=datetime(2025,5,10,18,0,0),
        from_location=munich.id,
        to_location=amsterdam.id,
        limit=10,
    )

asyncio.get_event_loop().run_until_complete(search())

You can also add an HTTP proxy to connect via as Bahn tends to block server ip addresses.

from weiche import AsynchronousApi

api = AsynchronousApi(proxy="192.168.0.1:8888")

Response from Asynchronous API

The return format is an object which can also be found in the objects.py file.

Look for the Connection class and see the API definition there.

Use the schiene compatibility layer

from weiche import Schiene

Schiene().connections('Mannheim HbF', 'Stuttgart HbF')

You can also add an HTTP proxy to connect via as Bahn tends to block server ip addresses.

from weiche import Schiene

api = Schiene(proxy="192.168.0.1:8888")

Response from Schiene Layer
